ALLEN PARK -- The Detroit Lions used the No. 199 pick in the sixth round of the 2013 NFL draft to select Notre Dame running back Theo Riddick. The Lions acquired the pick in an earlier trade with the Seattle Seahawks.

Recruited as a running back, Riddick was converted to a slot receiver, where he played through his junior year. Over the past three seasons he averaged 38 receptions.

As a senior, Riddick was shifted back to running back. As the team's primary ball carrier in 2012, he gained 917 yards on 190 rushing attempts.

Riddick also has handled return duties as a freshman, averaging 22.9 yards on 37 attempts that season. He did not return punts for the Irish.

On the short side at 5-foot-10, Riddick has good bulk, weighing 201 pounds. Obviously, he has displayed the versatility the Lions like in players.
